UNITED STATES PATENT OFFIC GEORGE E. NEWELL, OF PAIVTUCKET, RHODEISLAND.

HOISTlNG-BUCKET.

SPECIFICATION forming part of Letters Patent No. 396,664, dated January22, 1889.

Application filed August 6, 1888.

To all whom it may concern:

Be it known that I, GEORGE E. NEWELL, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Hoisting-Buckets,of which the following is a specification.

My invention relates to that class of hoisting-buckets which are adaptedfor the purpose of lifting coal from the hold of a vessel; and itconsists in providing the bucket with a powerful opening movement, ashereinafter fully set forth.

Figure 1 represents a top view of a hoisting-bucket provided with myimprovement. Fig. 2 represents a vertical section taken in the line itof Fig. 1. Fig. 3 represents a corresponding section with the bucketsopen. Fig.4 is a similar view showing a modification of thepower-multiplying movement for opening the bucket.

In the accompanying drawings, A A are the opposite holding jaws of thebucket, which are pivoted to each other by means of the bolt a, whichpasses through the lever Z), attached to the jaw A, and the arm Z),which connected to the jaw A. The arm Z) will thus be pivoted to thelover I) at a point intermediate of its ends.

At the adjacent inner corners, g, of the jaws A A are j ournaled thedrums 1-3 B, which are provided with enlarged wheels 7a, to which thehoisting ropes or chains C and I) are respectively attached. Thehoisting rope or chain (passes upward from the wheel it, to theperiphery of which it is attached, through the guiding-eve c, t'm'med atthe side of the lever 11, and which is provided with the friction -wheel(I, and the hoisting rope or chain I) passes upward from the wheel it,to the periphery of which it is attached, and through the guiding-eye(2, formed at the side of the arm I), and which is provided with thefriction-wheel f, the said friction-wheels d and f being made to turnloosely upon the connectingbolt a.

To the cornersgg of the jaw A are attached the ropes or chains E, thesaid ropes or chains passing over the sheaves of the pulley-blocks F,which are attached to'the sides h of the jaw A, the said ropes or chainshaving their ends attached to the drum B at the points'i, so that whenthe wheel 71: and drum B are Serial No. 282,086. (No model.)

turned in the proper direction the jaws A A will be drawn toward eachother with a twofold purchase, and when the wheel 7; is made of twicethe diameter of the drum l a pull upon the hoisting rope or chain 0 willcause the closing of the jaws A A with a fourfold purchase, thussecuring a powerful closlng movement upon the coal to be lifted. To theouter end of the lever b is attached the rope or chain G, the oppositeend of which is attached to the drum B at the point j. The wheel 70,being made about twice the diameter of the drum 1%, will cause the jawsA A to be thrown open with a twofold purchase when pulling upon the ropeor chain D, which is attached to the periphery of the wheel it.

Instead of the wheel 7;. and drum 1%, as above described, equivalentpulley-blocks, .T and K, may be employed, as shown in Fig. 4:, in whichcase the rope or chain D may pass around the wheel or sheave 70 of thepulleybloek J, which is attached to the fixed rod I, connecting the twoopposite corners of the bucket-jaw A, and thence around the sheave ofthe pulley-block K, attached to the outer end of the lever Z), and haveits end fastened to the block J at the point m, and by this means thebucket will be thrown open with a twofold purchase, as before, whenpulling upon the rope or chain D. In order to still further increase theleverage for opening the jaws, an. additional number of sheaves can beemployed in the pulley-blocks with a corresponding increase of power foropening the bucket. Instead of the red I, the pulleyblock J may beattached to the edge I of the bucket-j aw A, with a correspomlingincrease in the length of the lever Z); or the rod I can be placed atany intermediate point.

I claim as my invention In a hoisting-bucket, the combination, with thebucket-jaw and lover, of the opposite bucket-jaw pivoted to the saidlever at a point intermediate of its ends, the guided rope or chain C,for closing the bucket, the guided rope or chain G, which is operativelyc011- nected with the outer end of the lever, and the power-multiplyingmovement for opening the bucket, substantially as described.
